Abstract
The resistivity, thermopower, dc magnetic susceptibility and electron paramagnetic resonance (EPR) spectra of ZrNi 1− x Mn x Sn solid solution with low (0.001≤ x≤0.05) Mn concentration were investigated in the 78–400 K temperature range. Polycrystalline samples of the ZrNi 1− x Mn x Sn compounds were prepared by arc-melting of the pure metals. Quantitative atomic emission spectroscopy confirmed the appropriate Mn contents in all alloys. The lattice parameters of the ZrNi 1− x Mn x Sn compounds with different Mn concentration are almost unchanged. Magnetic susceptibility shows the linear dependence versus inverse magnetic field for all samples, what is evidence for the magnetic interactions in the ZrNi 1− x Mn x Sn compounds. The temperature dependence of magnetic susceptibility for the compounds with 0.005≤ x≤0.05 can be described approximately by a Curie–Weiss law. The results of static magnetic measurements were confirmed by EPR technique. The broad line of I type belongs to Mn 2+ ions in the Ni-sites in crystal lattice coupled by magnetic dipolar interaction. The narrow line of II type is interpreted as an EPR spectrum of exchange-coupled pairs or clusters of more than two Mn 2+ ions. The unusual magnetic properties and the features of dipolar and exchange interaction of the Mn 2+ ions in the lattice of ZrNi 1− x Mn x Sn solid solution are discussed.
